The Excel Odd function rounds a supplied number away from zero (i.e. rounds a positive number up and a negative number down), to the next odd number.
The syntax of the function is:
Where the number argument is the numeric value that you want to round.
In column B of the following spreadsheet, the Excel Odd function is used to round several different numbers.
The above examples show how the odd function always rounds away from zero, to the next odd number. I.e. If the supplied number is positive, it is rounded up (more positive), but if the supplied number is negative, it is rounded down (more negative).
If the number argument is exactly equal to zero, as shown in cell B4 of the example spreadsheet above, the Excel Odd function rounds to the positive value +1.
